Parking survey or parking stress report
A survey of on-street parking demand around a site, often needed for planning applications that add homes or remove parking.
About this service
Adding homes in London usually adds demand for kerbside parking, and councils want evidence that the nearby streets can cope. A parking survey, often called a parking stress survey, measures how full the surrounding roads are overnight, when most residents are at home. The results tell planning and highways officers whether your scheme is likely to make an existing parking problem worse.
Surveys are typically needed for conversions of houses into flats, new infill homes, and schemes that remove off-street parking or a garage. Many inner London boroughs require new homes to be car-free, with occupiers unable to obtain residents' permits, and in that case a survey may not be needed at all. In outer boroughs, where car ownership is higher, a survey is often a validation requirement.
We have completed parking surveys on 8 projects in London. Our reports set out the method, the streets surveyed, the kerb space available and the resulting stress level, in a format planning officers recognise, with plans showing each street and its result. Parking is often one part of a wider transport picture, so we can also prepare a transport statement where the council asks for one.
When you need it
- The council needs evidence of parking stress
- Your scheme adds homes with limited parking
What's included
- Overnight parking surveys to recognised methodology
- Analysis of parking capacity and stress
- Report for planning
How it works
- Agree the scopeWe check the council's requirements and agree the survey area, usually the streets within a short walk of the site, along with the survey nights and the restrictions to record.
- Measure the kerbsWe map every length of kerb in the survey area, excluding dropped kerbs, junctions, bus stops and other restricted sections, to work out how many cars can legally park.
- Carry out overnight countsWe count parked vehicles on weekday nights outside school holidays, when residential demand is highest, recording vehicles in each section of each street and noting any parked illegally or across dropped kerbs.
- Analyse and reportWe calculate parking stress street by street and for the whole area, estimate the extra demand from your scheme, and set out the findings in a report for planning.
What you receive
How councils read a parking stress result
Parking stress is the number of parked cars as a percentage of the available kerb space. Many London councils treat stress above roughly 85 per cent as the point where drivers struggle to find a space, though each borough sets its own expectations. A result below that level, with your scheme's added demand included, is generally good news. A result above it does not automatically mean refusal, but it shifts the conversation towards car-free development or other mitigation.
Timing and method decide whether a survey is accepted. Surveys carried out in school holidays, on Friday nights or during unusual local events can be rejected, as can those using the wrong survey radius or the wrong kerb length per car. Agree the method with the council before surveying if there is any doubt. If your scheme also creates new off-street spaces, a swept-path analysis shows that cars can actually use them.

Frequently asked questions
What is a parking stress survey?
It is an overnight count of parked cars on the streets around a site, compared with the length of kerb available for parking. The result, expressed as a percentage, shows how close the area is to capacity. Councils use it to judge whether a development that adds homes or removes parking would put unacceptable pressure on local streets.
When is a parking survey needed for planning?
Usually when a scheme adds homes with little or no off-street parking, or removes existing parking, in an area where kerbside demand is high. Councils often list it on their validation checklist. If your borough already requires new homes to be car-free with no permit eligibility, a survey may not be needed, so check first.
How long does a parking survey take?
The counts are made on specific weeknights, so the timing depends on the dates agreed and on avoiding school holidays. The report follows the surveys. We confirm the programme, based on our typical turnaround of 10 working days, in writing with the fee before we start.
How much does a parking stress survey cost in London?
Our parking survey and stress report starts from £850 + VAT. The fee depends on the size of the survey area and how many nights the council requires. Every job starts with a fixed fee confirmed in writing before any work begins, so you know the cost before any surveys are booked.
What happens if parking stress is too high?
It does not always mean refusal. Common responses are making the scheme car-free with a legal agreement preventing residents' permits, reducing the number of homes, providing off-street spaces or car club access, or improving cycle parking. The planning officer will advise which measures they consider acceptable for your site.
